What is Specificity? Why it’s so misunderstood

I personally believe this is such a misunderstood term, the  principle  of  specificity  is  one  of  the  least  well-understood  concepts  in  strength  and conditioning or by coaches in many sports.

Broadly speaking, the principle of specificity states that any training conducted by an athlete should be specific to their sport.  This maxim should be interpreted in a general sense.  All sports require an athlete to have a number of qualities to be successful (for example, skill, speed or strength).
